angustior, Zippora [ Rissoa angustior (Monterosato, 1917) ] ( Figures 13D–F )

1917: 11, pl. I, fig. 9 [LXVII: 1285, 1305, fig. 9]—available name

Type material. MCZR –M–30008 —6 sh “ Z. angustior Typ. 1917 Monts Tripoli !!”

Type locality. Described from Tripoli ( Libya).

Remarks. MolluscaBase (2018) considers it as a nomen dubium, as did Verduin (1985) who pointed to his R. rodhensis for a possible link; however, not having seen the types, he kept R. angustior as nomen dubium. Pending a revision with genetic data of the Mediterranean Rissoa , we keep R. rodhensis and R. angustior (both with paucispiral protoconch) as distinct species, based on a few morphological features (more robust shell, less expanded outer lip, violet sutures in R. angustior ) that however need further testing.
